I have a rover. But I want to change the forward motion and the backward motion. I tried to change the pins of the H Bridge. This did not bring the desired result.

How can I change the orientation of the rover? I use this upside down.

The left-right movement is correct. But currently the rover is driving backward in my current usage.

I want to turn the arrow keys on the keyboard. Forward is backward and forward Backward is forward.

I hope you can help me.
